Object

column r/w SNMPv2-TCTruthValue 
The value of tnPortEtherDownWhenLoopedEnabled specifies whether
physical loop detection for the Ethernet port is enabled or
disabled.  When enabled, the port will periodically send out
keep-alive PDUs with an EtherType of 0x9000.  If the port
receives a keep-alive that it transmitted, tnPortState will be
set to 'linkUp' if it was previously 'up'. The port will not move
back to tnPortState 'up' for a period of time defined by
tnPortEtherDownWhenLoopedRetry, but will continue to periodically
send out keep-alive PDUs.  Every time the port receives a keep alive
it sent while a loop has been detected, it will reset the time
period that it will remain down as defined by
tnPortEtherDownWhenLoopedRetry.
